T'was not only the local natives that the Coastwatchers had to be concerned with.
At one point, our esteemed Australian Broadcasting Commission's radio news reported on a Japanese raid being successfully intercepted following information received from "a coastwatcher on Bougainville".
Sadly, the censors did not pick it up before broadcast and the next (and last) transmission from the poor chap was that the Japs were hunting him with dogs.
